Sunflower seeds are fruits of the sunflower (Helianthus annuus), present in the human diet since ages ago. The sunflower seeds have a very high energy value, 580 kcal per 100 grams; they are a rich source of fiber (11 g/100g) and have a high content of certain minerals and vitamins. The roasted sunflower seeds contain mostly the minerals such as copper, phosphorus, selenium and manganese, but the contents of zinc, potassium, magnesium and iron are also considerably high. Vitamin E is dominant, but high contents of pantothenic acid, vitamin B6 and niacin are also present..
Copper plays an important role in the metabolism of proteins and the healing process, but it also enhances the iron absorption.
Phosphorus, along with calcium, is essential in the building of bones and teeth, but it plays an important role in the transport of energy to the cellular level.
Selenium has a similar metabolic function in the human body to vitamin E, it acts like an antioxidant, protecting hemoglobin and enhancing the proper functioning of the thyroid gland.
Manganese is an essential component in the metabolism of carbohydrates, fats and proteins, but it also acts like an element which enhances the functions of the brain and the nerves.
Vitamin E plays the role of an antioxidant in the human body, but it also takes part in the building of red blood cells, regulating the muscle and gland activity.
